Description
Technical field
The present invention relates to a kind of lubricating oil, and in particular to a kind of special machine for improving turbocharged engine burn oil phenomenon
Oil and preparation method thereof.
Background technology
Lubricating oil is used in all kinds automobile, plant equipment reducing the liquid of friction, protection machinery and workpiece
Lubricant, acts primarily as the effects such as lubrication, cooling, antirust, cleaning, sealing and buffering.Lubricating oil is typically by base oil and additive
Two parts are constituted.Base oil is the main component of lubricating oil, decides the fundamental property of lubricating oil, and additive can then make up and change
The deficiency of kind base oil aspect of performance, gives some new performances, is the important component part of lubricating oil.
Due to the requirement more and more higher of environmental protection and automobile emissions standards, make turbocharged engine increasing
Automobile vendor adopts.And turbocharged engine with its advanced technology, powerful and save fuel oil the features such as, it is also more and more
Approved by user vehicle.According to statistics, the ratio of China's new car assembling turbocharged engine in 2014 is 12.2%, 2015
Year reaches 17.5%, and the year two thousand twenty this ratio will be more than 45%.
Although turbocharged engine has many advantages, but its " burn oil " phenomenon for occurring again and again, also allows numerous car owners
Extremely have a headache.Turbocharged engine " burn oil ", is exactly that consumption of lubricating oil is too fast in fact, and this is set with turbocharged engine
Meter is closely related with operation principle.
The gap of the 1st, design principle of turbocharged engine --- cylinder and piston is wider, be easier burn oil
Metal has a phenomenon expanded with heat and contract with cold, and when turbine runs, the gap between cylinder and piston will be because of
The quick rising of temperature and diminish, so turbocharged engine must when design with respect to naturally aspirated engine at the beginning
Broader cylinder and piston gap is reserved, in order to avoid after high-temperature expansion, cause part extruding impaired.So car is run at the beginning
When, in the case of identical viscosities machine oil, turbocharged engine has more machines relative to naturally aspirated engine
Oil gas is altered into combustion chamber, forms burn oil.
2nd, the operation principle of turbocharged engine --- combustion chamber operational temperature is higher, machine oil easily volatilizees
For turbocharged engine, high-temp waste gas directly act on turbine, then by metal heat-conducting, are delivered to cylinder body
On, then the temperature potential in crankcase can also must be raised, and temperature is higher, and the volatilization of machine oil is also bigger, then the machine of burn oil
Rate also will be higher.And naturally aspirated engine does not have exhaust gas turbine, the temperature in crankcase is accordingly lower, machine oil volatilization
Also can be less.
Most automobiles for being equipped with turbocharged engine are all recommended to be sent out with the fully synthetic of 5W-40 viscosity grades or synthesis
Motivation oil.
Want to solve " burn oil " phenomenon of turbocharged engine, just must be before 5W-40 engine oil low temperature requirements be met
Put, pay special attention to open flash point, three key indexs of evaporation loss and high-temperature high shear viscosity of engine oil.
Firstth, the flash-point of engine oil must be high.High-flash advantageously reduces machine caused by the high temperature of turbocharger
Oil-breaking is volatilized.
Secondth, the evaporation loss of engine oil must be low.This index is test machine oil evaporation situation at high temperature,
Test typically with NOACK Angelika Noacks method.
3rd, the high-temperature high shear viscosity HTHS of engine oil must be high.This index is examination machine oil in high temperature shape
Oil-film retention property under state.High HTHS can not only increase the sealing of piston ring and cylinder inner wall, while also can control due to cylinder
The lubricating oil that EVAP is not freely produced caused by interior direct-injection is diluted the phenomenon for causing viscosity to diminish.
The base oil that hybrid-engine oil is adopted in the market is three class hydrogenated base oils mostly, the machine oil product for mixing
Although disclosure satisfy that the standards such as API are required, using the phenomenon that burn oil cannot be solved on turbocharged engine.
The content of the invention
It is an object of the invention to overcome defect present in background technology, there is provided one kind improves turbocharged engine burning
Special engine oil of machine oil phenomenon and preparation method thereof.
The technical scheme is that：A kind of special engine oil for improving turbocharged engine burn oil phenomenon, including base
Plinth oil and additive；The base oil includes that polyester, polyol ester, synthesis alkene (PAO), synthesizing alkanes, alkylnaphthalene, II classes add
Hydrogen base oil, the additive include complexing agent, viscosity index improver and pour-point depressant.
Further, the special engine oil for improving turbocharged engine burn oil phenomenon, including following mass fraction
